CVE-2026-78555
Overview
CVE-2026-78555 is a known-severity vulnerability. It was published on August 24, 2026.
Technical Description
RansomLook exposed complete API keys in the HTML source of the authenticated /admin/apikeys administration page. Although the interface displayed only a shortened representation of each key, the full token was embedded in hidden form fields used by the enable/disable, private-access, and delete actions.
As a result, API credentials could be recovered by inspecting the page source or DOM. The credentials could also be unintentionally exposed through components that retain or inspect HTTP response bodies, such as debugging proxies, browser caches, monitoring systems, or other intermediaries. An attacker obtaining one of these tokens could subsequently authenticate using the privileges assigned to that key, including access to private data where the key was granted such permissions.
The patch removes API keys from subsequent page rendering and replaces them with SHA-256-derived opaque handles. Administrative actions submit only these handles, which are resolved back to the correspondi
